Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20S is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 35 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20S
The AirTAC SDAJ100X55-20S is a compact double-acting single-rod cylinder featuring an external extend stop. By turning the R (M27x2.0) adjuster screw, you can dial the forward stroke down by up to 20 mm directly on the machine, yielding a usable extend range of 35-55 mm without swapping shims or parts. Retract remains at the full 55 mm. Because the adjuster sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit features a robust 32 mm piston rod and a PT3/8 air port. Its short riveted body drastically saves axial mounting depth where a larger profile cylinder will not fit. The included -S piston magnet supports AirTAC reed or electronic switches for end-position sensing. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 35 – 55 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 20 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20S Is Used
Press Fit Dialing
Fine-tune the 35-55 mm extend stop on heavy press operations to achieve exact insertion depths without machining custom spacers.
Vertical Lift Stops
Lift loads up to 200.2 kg safely with a 2:1 margin, adjusting the mechanical stop to prevent over-travel during payload changes.
Assembly Line Changeover
Rapidly reconfigure end positions on multi-product assembly lines using the M27x2.0 adjuster screw to switch part heights quickly.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20S the Right Cylinder?
When sizing this model, evaluate your force requirements against neighbouring bores. Stepping down to an SDAJ80 provides 2513.3 N push at 0.5 MPa, whereas this 100 mm bore delivers 3927 N. If your application demands even more power, a larger custom solution is required. The computed safe working load is approximately 2356 N, representing about 60% of the 0.5 MPa push figure, making it suitable for vertical lifts up to 200.2 kg with a 2:1 safety margin.
This cylinder is built for heavy setups requiring frequent changeovers or trial positioning. Confirm your specifications: 100 mm bore, 55 mm maximum stroke, 20 mm adjust window, PT3/8 port, female M18x1.5 rod thread, and the built-in magnet. Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–55 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M27×2.0 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-20S FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw shortens the extend end position by up to 20 mm, giving a 35-55 mm range; retract is unaffected. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
